Many boaters do not pull their boat out of their docking slip during winter. A potential danger is the water freezing around the boat. Installing an ice eater is a necessary winterization step for boaters who chose to keep their boat in the water over winter. Ice Eaters circulate the water around the boat to prevent ice from forming around the boat, marina, dock, and pier. We carry Ice Eaters from Powerhouse that are easy to install and use.
